Discussion
The purpose of timestamping is to avoid the use of locks.
Answer: A
Correct answer: True
Timestamping assigns each transaction an order in advance and resolves conflicts by that order, so no transaction has to wait for a lock. This removes deadlock entirely, which is a substantial gain in a distributed system where detecting a deadlock spanning several sites is difficult. The cost is that a transaction found to be out of order must be restarted.
